So, I've been mining perfectly fine for a while until today. I had to reboot to test something, and when I did, whichever card I put in the bottom slot stopped working. I know the hardware is fine, and the bottom card works when the top card is out. This happened before I updated to 11.6, and everything was stable until now. CCC only sees the top card, although Afterburner and Windows see both. I tried enabling extended desktop, which did nothing. I don't think my dummy plug is the issue, but I will test that in a minute. When I run the top card alone, it works fine. When I run the bottom card alone, it only gets 300 kh/s. When I run them both together, they both get <1 mh/s. Help!
